Solar Hot Air Collector

Status: Completed

This is a look back at a project from 2006-2008. The concept is based on similar projects using panels with metal sheet plates, pop cans, and similar systems to gather solar energy in a passive collector. A fan is used to circulate air through a closed duct system, heating the air as it flows through the area heated by the sun.

Ducts and foam glued in place with silicon (regular and high heat for top box) (~$15)

3M 5200 Adhesive/Selant to seal glazing to frame. (~$15)

Assembly brackets, rivets, etc (~$25)

Mounting aluminum angle iron 8′ (~$35)

Collector box front aluminum panels ~1/16 10.5″X4′ (~$15)

Total materials cost approx $625-$725 depending on materials used and current pricing.

All prices are approx in $CDN before taxes.

Heating Performace:

Under clear bright conditions at mid day typically see a ~40F-45F temperature rise from inlet to outlet (from ~65-70F in to ~100-115F out). Air is ducted from basement floor through unit and out into basement ceiling.
